On the higher ground, the Germans continued to inflict many losses on the British divisions beyond Langemarck but on 19 August, after two fine dry days, XVIII Corps conducted a novel infantry, tank, aircraft and artillery operation. German strongpoints and pillboxes along the St Julien–Poelcappelle road in front of the {{lang|de|Wilhelmstellung}} were captured. On 22 August, more ground was gained by XIX and XVIII corps but the tactical disadvantage of being overlooked by the Germans continued.{{sfn|Edmonds|1991|p=203}} A II Corps attack on the Gheluvelt Plateau from 22 to 24 August, to capture Nonne Bosschen, Glencorse Wood and Inverness Copse, failed in fighting that was costly to both sides.{{sfn|Edmonds|1991|pp=202–205}} Gough laid down a new infantry formation of skirmish lines to be followed by "worms" on 24 August and Cavan noted that pillboxes should be attacked on a broad front, to engage them simultaneously.{{sfn|Simpson|2001|pp=130–134}} Another general offensive intended for 25 August, was delayed by the failure of the preliminary attacks and then postponed due to more bad weather.{{sfn|Rogers|2010|pp=162–167}} On 27 August, II Corps tried a combined tank and infantry attack but the tanks bogged, the attack failed and Haig called a halt to operations until the weather improved.{{sfn|Edmonds|1991|p=208}}
